The aim of the monitoring was to increase knowledge on the vaults behaviour during the outer filling loads application. 30 sensors were installed on one characteristic section. Fiber optic sensors are integrated in the global concept together with inclinometers, thermometers, load cells, piezometer cells and geometric measurement. 

INSTALLATION PERIOD TYPE OF SENSORS NUMBER OF SENSORS
2000 – 2003 SOFO 6

Aim of monitoring:
Behaviour and stabilization of the cut and cover tunnel has been verified at each phases of the filling.
